Fun With Magnets - Free MCQ Test solutions, Class 6 1000+ Questions

Magnetic field lines are directed from North Pole to South Pole outside the magnet and south pole to north pole inside the magnet.. So option (d) is correct.    

Like poles of magnets repel each other.

- Container (i): Copper coin and iron nail
- A magnet can attract the iron nail but not the copper coin.

- Container (ii): Iron and wood
- A magnet can attract the iron but not the wood.

- Container (iii): Marble and cloth
- Neither object is magnetic, so a magnet cannot separate them.

- Container (iv): Nickel coin and paper bits
- A magnet can attract the nickel coin but not paper bits.

Thus, Reeta can use a magnet to separate objects in containers (i), (ii), and (iv). Therefore, the correct answer is A: (i), (ii), and (iv).

When a bar magnet is immersed in a heap of iron filings and pulled out, the iron filings cling to both poles of the magnet. However, the distribution of filings is generally symmetrical. Both the north and south poles of the magnet attract a nearly equal amount of iron filings, as both poles produce strong magnetic fields, though they may appear slightly different due to the nature of the magnetic field lines.

Thus, the correct answer is A: North pole is almost equal to the south pole.

A compass has a needle that is magnetized and points towards the Earth's magnetic poles. The needle in a compass is indeed a magnet, which aligns itself with the Earth's magnetic field, helping users determine directions.

Thus, the correct answer is C: Compass.

A magnet can be used to separate iron filings from sand because iron is magnetic, while sand is not. The magnet will attract the iron filings and leave the non-magnetic sand behind.

Thus, the correct answer is A: Iron filings from sand.
Other options are incorrect because magnet does not attract copper or aluminium foil

We know that poles are the areas of the strongest magnetism in a magnet. That means the force of attraction or repulsion in a magnet is strongest at the poles. Like poles always repel each other while unlike poles always attract each other. Here, the south pole of the bar magnet X is facing towards the north pole of the bar magnet Y. Hence, magnet Y will be attracted by the magnet X. The two south poles of bar magnets Y and Z are facing towards each other. Hence, the magnets Y and Z will get repelled. Thus, we can conclude that magnet Y will get attracted towards magnet X and repelled by magnet Z.

• Marble (a) – Marbles are typically made of glass or ceramic, which are not magnetic.
• Toothpick (b) – Toothpicks are made of wood, which is also non-magnetic.
• Ten-cent coin (c) – Most ten-cent coins are made from non-magnetic metals such as copper, nickel, or aluminum, which are not strongly attracted to magnets.
• Steel ball bearing (d) – Steel contains iron, which is strongly attracted to magnets.

Since the matchbox moves when the magnet is brought near, the most likely object inside is the steel ball bearing (d).

Copper is a non-magnetic material, meaning it is not attracted to a magnet. On the other hand, cobalt, iron, and nickel are all magnetic materials, meaning they are attracted to magnets.

Thus, the correct answer is D: Copper.

When a magnet is broken into pieces every piece will have 1 pair of north and south pole.
So if its broken into 6 pieces then each piece will be having one north pole and one south pole. So 6 north poles and 6 south poles, combined will be 12.

Since like poles repel each other, magnet P will repel magnet Q.

Materials that are attracted to a magnet are called "magnetic" materials. These materials are influenced by a magnetic field, unlike non-magnetic materials which are not attracted to magnets.

Thus, the correct answer is D: Magnetic.

Magnetic force can be both a pulling (attractive) and pushing (repulsive) force depending on the poles interacting.

Soft iron placed across the poles will preserve the magnetism for a long time.

We know that every magnet has two poles, one north pole and one south pole. The force of attraction or repulsion in a magnet is strongest at the poles. Like poles always repel each other while unlike poles always attracts each other. Thus, we can say that P and Q are the magnets here. R is not a magnet, as when its both ends are brought near to magnet, its North pole remains stationary. For the magnet P, X is the north pole and Y is the south pole whereas for magnet Q, X is south pole and Y is north pole.

Magnets come in various shapes, including cylindrical, ball-ended, and horseshoe shapes. Each shape has different applications depending on the use, but all of these are valid forms of magnets.

Thus, the correct answer is D: All of these.

Answer: B) North pole
The North Seeking Pole of a magnet is the pole that is attracted to the Earth's magnetic south pole, pointing towards the magnetic north.

The effect of magnetic field cannot pass through any metal. Magnetic effects can pass through screens of substances such as plastic, paper, glass etc.

Poles 1, 3 and 5 are like poles, so they will not attract each other. Similarly poles 2, 4 and 6 are like poles. Only unlike poles are attracted by each other.
